Fun game
Very addictive. I felt compelled to finish it, now matter how frustrating it got at times.
My biggest gripe is that it sometimes starts you off in an impossible situation. Twice, I started off going straight into a lake.
Also, you occasionally get a vertical line of obstacles, which can be damned near impossible to get through because of the slow recharge on the dynamite and matches. Speaking of those, sometimes the screen moves a little and you waste them on grass. Please make it so you can't activate matches or dynamite when you're not touching a tree or a mountain.
One last thing - the 90 degree track pieces are just about worthless. There aren't enough empty slots, so you almost never get lucky and receive two pieces that work together. Most of the time, you end up throwing them behind the train, just to get rid of them.
All in all, though, a great game. Some upgrades to the game play will make it very replayable.
